What is stainless steel?
Stainless steel is the steel that chromic content exceeds 12% is planted, it is a kind of big iron that has stainless steel character a general designation of its alloy steel.
What is the model that commonly used adornment uses stainless steel?

Is akin norms profile harder thicker?
Not certain. There is a part to break up on the market at present because produce technical limitation,make material, carbolic content is exorbitant contain a few nitrogen to bring about hardness to rise; Be like Cr, Ni to reduce content additionally, hardness also can rise, also can bring about material tenacity and corrosion resistance to drop relatively at the same time.

Is stainless steel scarcely rusty? Does adornment stainless steel rust below what condition easily?
Either. Adornment sends rusty corrode with stainless steel, besides the blemish of oneself, with located environment, if air humidity, temperature, air flows speed and direction, and the part that contains impurity and amount huge concerns. In air and weak caustic material, corrode rate to be less than 0.01mm/ year be thought namely " be able to bear or endure completely corrode " . But in CL- medium (be like salt) , the meeting in agent of clean of vitriolic, oxalic acid, hydrochloric acid, porcelain is rusty, neuter material should be used in conserve process (if rinse) often clean corrode medium in order to decrease to add stick and rust, should avoid acerb article cut additionally, influence exterior and destroy the union between brilliant and rust.

Why is stainless steel cold after be out of shape rust easily?
Turn of stainless steel course, twist, the meeting after folding produces a wrong appear (damage is united in wedlock to destroy between in-house brilliant namely) , produce spot corrosion easily and rust.

The classification of stainless steel
Stainless steel can press utility, chemical composition and metallographic organization to be classified roughly.
It is basic composition by 18% chromium, 8% nickel with the steel of abstruse type system, because each element joins the change of the quantity to differ, and the steel that develops all sorts of use is planted.
Press chemical composition classification: 1, CR series: Ferrite series, martensite series 2: CR-NI series: Series of series of abstruse type style, unusual series, separate out sclerosis
Organize classification by metallographic: 1, abstruse type stainless steel 2, iron element stainless steel 3, Martens stainless steel 4, double photograph stainless steel 5, precipitation sclerosis stainless steel

Chromium decides action mediumly in stainless steel
The element that decides stainless steel attribute has a kind only, it is chromic, every kinds of stainless steel contains a certain quantity of chromium. Up to now, had not contained chromic stainless steel. Chromium becomes the main element that decides stainless steel function, primary reason is after chromium is being added to serve as alloying element in Xiang Gang, make its in-house contradiction carry tendercy is helpful for resistance corroding destroyed field to develop. This kind of change can get demonstrative from the following respect:
1, chromium makes the electrode potential of iron radical solid solution extremely high.
2, the electron that chromium absorbs iron makes Tie Dun is changed. Passivation is the appearance that be prevented as a result of zincous reaction and causes metal and alloy corrosion resistance to be able to be raised. The theory that forms metal and alloy passivation is very much, basically film talking, adsorption talking and electron are arranged theory.

Nickel is in the effect in stainless steel just is produced after cooperating with chromium
Nickel is admirable anti-corrosive material, the important alloy that also is alloy steel changes an element, the element that forms austenite is in steel, but steel of low carbon nickel should be obtained pure organization of abstruse family name, the quantity that contain nickel should be achieved 24% ; And contain nickel to be measured only 27% when just make steel is in the corrosion resistance in certain medium can be changed significantly. Nickel cannot make stainless steel alone, but when nickel and chromium are put in stainless steel at the same time, the stainless steel that contains nickel has a lot of commendable property however, it can make the organization of tall chromium steel produces change, make thereby the corrosion resistance of stainless steel can and technical properties wins certain improvement.
